Introduction. The principles of reduction theory in the form of methods for detecting hidden patterns in data, approaches to transforming coordinate systems and reducing the dimensionality of input information are widely used in identifying and classifying objects, finding abnormal trends in financial activities, technical systems for measuring physical and chemical parameters.

The purpose of the paper is to review the theoretical and practical results of the application of the theory of reduction in problems and data processing systems.

Methods. Methods for detecting hidden patterns in data, classification of objects using alpha procedure, cognitive modeling of environmental data, frequency-time digital filtering, conversion and modeling of multicomponent signals, measuring concentrations of chemicals in the environment and the content of greenhouse gases in the earth atmosphere, determining the loads on the axis of the car on the signal of dynamic weighing, estimating the consumption of pulverized coal to save coke and natural gas blast furnace.

Results. Principles of the theory of reduction, highly sensitive analytical system “Analyzer SCP” for measuring concentrations of 20 chemicals in drinking water, food and the environment using three new pulsed chronopotentiometry methods for electrochemical analysis, information technology “Atmospheric gases” for determining concentrations of 38 gases atmosphere, computer systems of dynamic weighing of the car for customs weight control of vehicles.

Conclusions. For a class of problems with monotonic integrated measurement data, it is necessary to transform the coordinate system, which allows us to consider a multicomponent signal as the sum of individual components. The use of reduction theory methods has made it possible to develop intelligent information technologies for environmental monitoring of biosphere objects, effective technical systems for measuring physical parameters, and detecting fraudulent transactions in the banking system.

Keywords: reduction theory, hidden patterns, object classifications, coordinate system transformations, frequency-time filtering, concentration determination.
